Description

Technical Field

[0001] This utility model relates to the field of roller surface cleaning technology, specifically a roller surface cleaning device for casting and rolling rolls. Background Technology

[0002] Continuous casting rolls are rolls used for forming cast billets. They typically consist of a mandrel, a housing, and a protective layer. The protective layer is one of the most important components of the continuous casting roll, significantly determining the forming quality and surface condition of the cast billet. Currently, commonly used materials for continuous casting rolls include high-chromium cast iron, high-chromium-high-nickel cast iron, and high-chromium cast steel.

[0003] Most existing roller surface cleaning devices are cleaning brushes installed at the bottom of the thin strip continuous casting roller surface. When the thin strip continuous casting roller rotates, the surface of the roller is cleaned by the cleaning brush. However, it cannot completely clean some tightly attached metal debris, resulting in poor cleaning effect and damage to the steel plate. It is difficult to meet the actual use requirements and its practicality is not strong.

[0004] To overcome the aforementioned shortcomings, existing technology (Chinese patent application date: CN218425486U, filed on 2023-02-03) discloses a thin strip continuous casting roll surface cleaning device, including a continuous casting machine body and a roll body rotatably mounted on the continuous casting machine body. The bottom of the roll body is provided with a cleaning mechanism for cleaning metal debris from its surface. The cleaning mechanism includes a movable horizontal plate located at the bottom of the roll body and a limiting horizontal plate located at the bottom of the movable horizontal plate and slidably connected to it. An arc-shaped cleaning plate matching the surface of the roll body is fixed at the top of the movable horizontal plate, and a driving component for pushing its movement is provided at one end of the movable horizontal plate. This invention facilitates a more thorough cleaning of metal debris adhering to the roll surface, significantly improving the cleaning effect and enhancing the practicality of the cleaning device. It avoids the situation where the cleaning device cannot thoroughly clean some tightly adhered metal debris, resulting in poor cleaning effect and damage to the steel plate during cold rolling. It also facilitates the replacement of the arc-shaped cleaning plate.

[0005] While the above design can solve the aforementioned problems, the existing clamping design is not convenient enough when cleaning cast rolls of different sizes, resulting in reduced processing efficiency and insufficient clamping stability. This causes the equipment to shake during the cleaning process. Furthermore, the cleaning mechanism is not designed to move symmetrically during the rotation of different cast rolls, leading to insufficient cleaning efficiency and reduced applicability. Adjustments are required for processing conditions of cast rolls of different sizes. Utility Model Content

[0006] The purpose of this utility model is to provide a casting roll surface cleaning device to solve the problems mentioned in the background art, such as the inconvenience of the existing clamping design when cleaning casting rolls of different sizes, which reduces processing efficiency and clamping stability, causing the equipment to shake during the cleaning process. At the same time, the design of the cleaning mechanism is not easy to move symmetrically during the rotation of different casting rolls, resulting in insufficient cleaning efficiency and reduced applicability. The processing conditions of casting rolls of different sizes need to be adjusted.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a casting roll surface cleaning device, comprising a support stabilizing plate, a support lifting frame mounted on the upper surface of the support stabilizing plate, and a meshing transmission mechanism for moving a semi-circular support plate inward inside the support lifting frame, the meshing transmission mechanism comprising a fixed rotating frame, the fixed rotating frame being fixedly installed on the inner surface of the support lifting frame, an integral rotating worm gear mounted inside the fixed rotating frame, and a semi-circular meshing gear mounted on the outer surface of the integral rotating worm gear, an auxiliary support frame mounted on the upper surface of the support stabilizing plate, and a sliding elastic mechanism for moving a cleaning extension plate left and right inside the auxiliary support frame.

[0008] Furthermore, a reciprocating drive motor is installed on the outer surface of the auxiliary support frame, and a fixed transmission gear is installed on the outer surface of the output end of the reciprocating drive motor. A limit contact frame is installed on the side of the auxiliary support frame, and the cleaning extension plate slides along the interior of the auxiliary support frame in a limited manner.

[0009] Furthermore, a transmission rack is installed on the back of the cleaning extension plate, and the transmission rack meshes with a fixed transmission gear. An elastic auxiliary plate is installed on the outer surface of the cleaning extension plate, and the end of the elastic auxiliary plate slides along the inner surface of the auxiliary support frame.

[0010] Furthermore, the semi-circular meshing gear is rotatably mounted on the outer surface of the support lifting frame, and a connecting rotating rod is mounted on the outer surface of the semi-circular meshing gear. An engaging rotating component is mounted at the end of the connecting rotating rod, and a stabilizing disc is mounted on the upper surface of the support stabilizing plate.

[0011] Furthermore, the outer surface of the stabilizing disk is provided with a sliding inner groove, and the fitted rotating component slides along the inside of the sliding inner groove for a limited position. The integral rotating worm meshes with the semi-circular meshing gear, and the end of the integral rotating worm is rotatably installed at the center position of the stabilizing disk.

[0012] Furthermore, a semi-circular support plate is installed on the outer surface of the fitting rotating component, and the inner surface of the semi-circular support plate slides along the outer surface of the stabilizing disk. The fitting rotating component is rotatably installed at the end of the connecting rotating rod, and the fitting rotating component and the semi-circular support plate are designed as an integral unit.

[0013] Furthermore, the front end of the cleaning extension plate corresponds to the side of the stabilizing disk, and a side support rod is installed inside the stabilizing plate. The side support rod slides back and forth along the inside of the stabilizing plate, and the auxiliary support frame slides laterally along the inside of the stabilizing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the casting roll surface cleaning device needs to clamp casting rolls of different sizes, the side of the casting roll is directly put into contact with the stabilizing disc. At this time, the integrated rotating worm gear is directly rotated to drive the semi-circular meshing gears inward through the connecting rotating rod and the fitting rotating part. The four sets of semi-circular meshing gears will stably and synchronously mesh the outside of the casting roll. This design makes the clamping design more convenient, improves the processing efficiency and strengthens the clamping stability, so that the cleaning process of the equipment will always remain stable.

[0015] Furthermore, when external cleaning of the casting roll is required, the auxiliary support frame can be moved laterally as a whole, so that the front end of the cleaning extension plate contacts the casting roll. At this time, the auxiliary support frame can continue to slide forward, so that the elastic auxiliary plate keeps pressing and contracting backward to ensure the cleaning effect of the elastic auxiliary plate. In addition, the reciprocating drive motor will rotate left and right, so that the cleaning extension plate can clean the casting roll as a whole. This design makes the cleaning work more efficient and improves the applicability at the same time. No extra adjustment work is required for the processing conditions of casting rolls of different sizes.

[0016] Furthermore, during the side-end fixing of the casting roll, the side-end support rod is simultaneously slid laterally along the upper surface of the support stabilizing plate, so that the side-end support rod stably supports the other end of the casting roll and provides rotational power, resulting in higher stability of the processing.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a casting roll surface cleaning device, including a support stabilizing plate 1, a support lifting frame 2 installed on the upper surface of the support stabilizing plate 1, and a meshing transmission mechanism for moving a semi-circular support plate 12 inward inside the support lifting frame 2. The meshing transmission mechanism includes a fixed rotating frame 6, which is fixedly installed on the inner surface of the support lifting frame 2. An integral rotating worm 7 is installed inside the fixed rotating frame 6, and a semi-circular meshing gear 9 is installed on the outer surface of the integral rotating worm 7. An auxiliary support frame 5 is installed on the upper surface of the support stabilizing plate 1, and a sliding elastic mechanism for moving a cleaning extension plate 18 left and right is installed inside the auxiliary support frame 5.

[0026] like Figure 2 , Figure 3 , Figure 4The technical solution shown addresses the problem that existing clamping designs are inconvenient for cleaning casting rolls of different sizes, leading to reduced processing efficiency and insufficient clamping stability, causing shaking during the cleaning process. The solution discloses a semi-circular meshing gear 9 rotatably mounted on the outer surface of the supporting lifting frame 2. A connecting rotating rod 8 is mounted on the outer surface of the semi-circular meshing gear 9, and an engaging rotating component 10 is mounted at the end of the connecting rotating rod 8. A stabilizing disk 3 is mounted on the upper surface of the supporting stabilizing plate 1, and the outer surface of the stabilizing disk 3... A sliding inner groove 11 is provided, and the fitting rotating member 10 slides along the inside of the sliding inner groove 11 for limiting. The integral rotating worm 7 meshes with the semi-circular meshing gear 9, and the end of the integral rotating worm 7 is rotatably installed at the center of the stabilizing disk 3. A semi-circular support plate 12 is installed on the outer surface of the fitting rotating member 10, and the inner surface of the semi-circular support plate 12 slides along the outer surface of the stabilizing disk 3. The fitting rotating member 10 is rotatably installed at the end of the connecting rotating rod 8, and the fitting rotating member 10 and the semi-circular support plate 12 are integrally designed.

[0027] When side-end fixing of the casting roll is required, the integrated rotating worm 7 is directly rotated along the inside of the fixed rotating frame 6. Since the fixed rotating frame 6 is fixedly installed inside the support lifting frame 2, and the support lifting frame 2 is also fixedly installed on the upper surface of the support stabilizing plate 1, the integrated rotating worm 7 will be driven to rotate stably in a circular motion. During the rotation of the integrated rotating worm 7, the semi-circular meshing gears 9 that are in contact with each other on their outer surfaces will be driven to mesh and move. Since the center of the semi-circular meshing gear 9 is rotated and installed on the outer surface of the support lifting frame 2, the semi-circular meshing gear 9 will be driven to rotate continuously. As the semicircular meshing gear 9 rotates, the connecting rotating rod 8 fixedly installed on the outer surface will rotate synchronously. As the connecting rotating rod 8 swings, the fitting rotating part 10 rotatably installed at the end of the connecting rotating rod 8 will move inward. The movement of the fitting rotating part 10 will proceed along the sliding inner groove 11 opened at the corresponding position on the outer surface of the stabilizing disc 3. At the same time, the movement of the fitting rotating part 10 will synchronously drive the semicircular support plate 12 fixedly connected to the inner surface inward. Since the semicircular support plate 12 is a semicircular design, the four sets of semicircular support plates 12 will fix the outer surface of the end of the casting roll in a corresponding overall manner.

[0028] Example 2: Figure 1 , Figure 5 , Figure 6The technical solution shown addresses the problem that the cleaning mechanism is not easily designed to move symmetrically during the rotation of different casting rolls, resulting in insufficient cleaning efficiency and reduced applicability. It also discloses the need to adjust the processing conditions for casting rolls of different sizes. Specifically, a reciprocating drive motor 14 is mounted on the outer surface of the auxiliary support frame 5, and a fixed transmission gear 15 is mounted on the outer surface of the output end of the reciprocating drive motor 14. A limit contact frame 13 is mounted on the side of the auxiliary support frame 5, and the cleaning extension plate 18 slides along the interior of the auxiliary support frame 5 to maintain a limit. The back of the cleaning extension plate 18 is equipped with an integrated transmission rack 16, which meshes with the fixed transmission gear 15. An elastic auxiliary plate 17 is installed on the outer surface of the cleaning extension plate 18, and the end of the elastic auxiliary plate 17 slides along the inner surface of the auxiliary support frame 5. The front end of the cleaning extension plate 18 corresponds to the side of the stabilizing disk 3. A side support rod 4 is installed inside the supporting stabilizing plate 1, which slides back and forth along the inside of the supporting stabilizing plate 1. The auxiliary support frame 5 slides laterally along the inside of the supporting stabilizing plate 1.

[0029] When a comprehensive cleaning operation is required on the outer surface of the casting roll, the auxiliary support frame 5 is slid laterally as a whole, causing the cleaning extension plate 18 nested inside the auxiliary support frame 5 to move synchronously until the front end of the cleaning extension plate 18 touches the outer surface of the casting roll. At this point, the auxiliary support frame 5 can be moved further inward towards the casting roll. Under pressure, the front end of the cleaning extension plate 18 will slide outward along the interior of the auxiliary support frame 5. During this sliding process, the cleaning extension plate 18 will press against the elastic auxiliary plates 17 inside the auxiliary support frame 5, resulting in a tighter fit between the front end of the cleaning extension plate 18 and the casting roll. To achieve better cleaning results, the reciprocating drive motor 14, which is fixedly mounted on the outer surface of the auxiliary support frame 5, is started directly. The rotation of the reciprocating drive motor 14 will drive the fixed transmission gear 15, which is fixedly mounted on the outer surface of the output end, to rotate synchronously. During the rotation of the fixed transmission gear 15, the integrated transmission rack 16 will be driven. Since the integrated transmission rack 16 is fixedly mounted on the back of the cleaning extension plate 18, the cleaning extension plate 18 will be driven to slide laterally back and forth along the inside of the limit contact frame 13. During this process, the cleaning extension plate 18 can complete the external cleaning of the casting roller. The casting roller can be driven to rotate stably by the side support rod 4.
